The Flowserve PSS 4 Seal is a game-changer in the world of mechanical seals, offering outstanding performance, simplified installation, and robust reliability. As an industrial process seal engineered for high-demand applications, it brings unmatched benefits across a wide range of sectors such as oil & gas, chemical processing, power generation, and more.
What is a PSS Seal?
The PSS (Process Split Seal) is a semi-cartridge mechanical split seal developed by Flowserve. Designed with proprietary 3D Key face alignment technology, the Flowserve PSS 4 ensures perfect radial and axial alignment during installation. This significantly reduces installation time and risks of misalignment, which are common causes of leakage in conventional seals.
